crashing test case

Crash in AccessibilityRenderObject::activeDescendant when trying to set aria-activedescendant to something without a renderer

I could only get this crash to happen when using VoiceOver.  See the attached test case.  Just a simple nil check - I'll attach a patch soon.

Is there a way to trigger the accessibility API through DRT?
